Technical Overview

Defensive buildings must directly connect to at least 2 tiles of the Primus Conduit edge in order to receive the increase. You can connect a defense to 2 Primus Conduits at the same time, which will give you a multiplied increase in fire speed.

Tip: If the defense sparkles, it's being powered by the Primus Conduit!
